Final answer:
TENS (Transcutaneous Electrical Nerve Stimulation) is the method of pain control that is effected by the application of electrical impulses to the skin.
Step-by-step explanation:
The method of pain control effected by the application of electrical impulses to the skin is called TENS (Transcutaneous Electrical Nerve Stimulation).
TENS is a therapy that uses low-voltage electrical currents to relieve pain. The electrical impulses are delivered through electrodes placed on the skin, which stimulate the nerves and block pain signals from reaching the brain.
Example: When a person uses a TENS machine for back pain relief, the electrical impulses help to reduce the perception of pain and provide temporary pain relief.
